Specification of Letters Patent.

Application filed November 9, 1905- Serial Nn. 286,618.

To all whom it may concern.-

Be it known that 1, JOHN FREDERICK BER- TRAM, a citizen of theUnitedStates, residing at St. Louis, in the city of St. Louis and State ofMissouri, have invented a new and useful hurn-Dasher, of which thefollowing is a specification.

This invention relates to a churn-dasher designed to give a lurality ofcurrents to the cream when moved vertically in the churn.

A further object of the invention is to provide a dasher which can bereadily cleaned and which is adapted for use with churns of the ordinarybarrel construction.

The invention consists in two concentric disks, the upper one of whichis supported above the lower one by a plurality of strips arrangedalternately radially and tangentially with respect to the axis of thedasherrod, the disks and a portion of the strips being perforated.

In the accompanying drawings, Figure 1 is a side vertical elevation ofmy churndasher. Fig. 2 is an inverted plan view of the upper disk, thedasher-rod being shown in section of the line 2 2 of Fig. 1. Fig. 3 is asection of the line 3 3 of Fig. 1, two of the strips being also shown intransverse section.

In the drawings, A represents a dasherrod, to the lower end of which issecured a disk B, perforated, as shown at B, andhaving grooves formed.in its upper face, as shown at B, a port on of said grooves beingtangential with respect to the dasher-rod and each alternate groovebeing arranged radially with respect to the dasher-rod. An upper disk Cis provided with perforations C and has upon its end facetangentially-arranged grooves C and radially-arranged grooves C The diskC is centrally periorated to slide upon the dasher-rod A and issupported in position above and concentric with the disk that the stripsD and E are upwardly and inwardly inclined. To prevent the'upper diskfrom rising upon the dasher-rod while in use, a cotter-pin F is passedthrough the dasherrod A and locks the parts together, as shown .inFig. 1. By removing the cotter-pin the disk C can be readily removedfrom the dasher-rod A and the strips D and E also removed, thus makingit easy to thoroughly clean all parts of the dasher.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is-

1. A churn-dasher comprising a dash-rod, a disk fixed to the lower endof therod, a disk slidab'le on. the rod, a plurality of strips restingloosely on the fixed disk and supporting the slidable disk, and meansfor locking the slidable disk upon the upper ends of the strips.

2. A churn-dasher comprising a dash-rod, two concentric disks carried bythe rod, said disks being perforated, the opposing faces of said diskshaving alternately-arranged. radial and tangential grooves, and upwardlyand inwardly inclined strips adapted to space the disks apart, the endsof the strips engaging said grooves.
